Docker + Virtual Box = VT-x is not available (VERR_VMX_NO_VMX)
Virtualbox will get upset and not run if Microsoft Hyper-V is enabled.
Here's the solution:
- Open command prompt as administrator
- search for 'command'
- right-click then select 'run as administrator'
paste the following command:
dism.exe /Online /Disable-Feature:Microsoft-Hyper-VThen reboot.
To complete @DrDamnit answer, it is also possible to disable Microsoft Hyper-V from the menu.
- Search for "Turn Windows features on" on the start menu
- Disable Hyper-V
- Reboot your computer
Voilà
